The author presented innovative ideas of using digital cryptography—blockchain—which increases the efficiency of interactions that take place within the structures of modern cities or their fragments, between their users, in financial operations, public participation and administration and broadly understood services that use new digital media. Most of the presented examples refer to developing ideas that are in their testing phases and that we will soon be able to use as the most optimal ones.
